Description and Introduction

1A Low Dropout Adjustable Regulator 5-DDPAK/TO-263 -40 to 125 The **LM2941SX/NOPB** is a low-dropout (LDO) voltage regulator manufactured by **National Semiconductor (NS)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage Options:** 5V, 8V, 10V, 12V, 15V (fixed) or adjustable (1.275V to 26V)  
- **Output Current:** Up to **1A**  
- **Dropout Voltage:** Typically **0.5V** at full load (1A)  
- **Input Voltage Range:** Up to **26V**  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** **TO-263 (D2PAK-5)**  

### **Descriptions:**  
- The **LM2941SX/NOPB** is a **positive voltage regulator** with low dropout, designed for battery-powered applications.  
- It includes **thermal shutdown** and **current limit protection** for enhanced reliability.  
- Suitable for **automotive, industrial, and consumer electronics** applications.  

### **Features:**  
- **Low Dropout Voltage** (0.5V typical at 1A)  
- **Reverse Battery Protection** (up to -50V)  
- **Internal Short-Circuit Current Limiting**  
- **Thermal Overload Protection**  
- **Adjustable or Fixed Output Voltage Options**  
- **Low Quiescent Current in Standby Mode**  

This regulator is designed for **high-efficiency power management** in systems where input voltage is close to the output voltage.
